If you're aiming foror IB, they recommend you need to go to an M7 school, or t15 at the lowest. Getting those long-hour, high-paying, prestigious consulting and finance gigs is what draws many to the M7.
But what if you don't care about consulting or finance, but want a $100,000+ f500 job that's 50-60 hours? Say something in marketing, brand management, rotational programs,, corporate strategy, operations, sales, business development, product management, leadership development, etc.
What MBA programs would be worth the time, effort, and cost if six-figure f500 jobs are your goal? M7? T15? T20? T30? T50? Etc. Of course getting these positions isn't a walk in the park, but they seem a lot lessconsulting or finance. So for f500, I doubt it's "M7 or bust."
